Abstract :
A novel W-band (75-110 GHz) exposure system was designed, characterized and tested to be used for identifying millimeter wave (MMW) exposure parameters (frequency, modulation schemes and electric field magnitude) that could accelerate recovery from fatigue in skeletal muscle. The system designed allows electrical stimulation of muscle and measurement of contractile force during MMW exposure within an organ bath under conditions where the temperature of the muscle is maintained at 35 ± 0.2° C. Design and characterization of the exposure system were performed using the Finite-Difference Time-Domain numerical method and experimental measurements. Exposure experiments verified the penetration of the electric field into the muscle.
